摘要： An MRAM device has a new type of memory bank (10) that includes bit lines (21-24), a reference line (27) and digit lines (25, 26), on intersections of bit lines and digit lines a plurality of magnetic memory cells (15-18) are arrayed. Bit lines are formed on both sides of the reference line on a substrate. Since each bit line is fabricated closely to the reference line, each cell has substantially the same hysteresis characteristics, which allow the MRAM device to provide a steady operation mode.

摘要： A magnetoresistive random access memory architecture free of isolation devices includes a plurality of data columns of non-volatile magnetoresistive elements. A reference column includes non-volatile magnetoresistive elements positioned adjacent to the data column. Each column is connected to a current conveyor. A selected data current conveyor and the reference current conveyor are connected to inputs of a differential amplifier for differentially comparing a data voltage to a reference voltage. The current conveyors are connected directly to the ends of the data and reference bitlines. This specific arrangement allows the current conveyors to be clamped to the same voltage which reduces or removes sneak circuits to substantially reduce leakage currents.

摘要： A high speed and high density magnetoresistive random access memory (MRAM) device (30) is provided. The MRAM device employs a poly-silicon word line (39a) that saves wiring space. Further, the word line is connected to a digit line (38a) by a connecting line (44a) which reduces a electrical resistance between transistors (43a) and (40a). Arrangement of the connecting line reduces a transmission time from a digit current control (33a) to transistor (43a) and greatly improves a memory cycle time.

摘要： A non-volatile, bistable magnetic tunnel junction (MTJ) register cell includes first and second magnetic tunnel junctions connected for differential operation. The first MTJ is coupled between an easy axis line and an output terminal and the second MTJ is coupled between an inverse easy axis line and an inverse output terminal. A hard axis line is coupled magnetically to the MTJs and an enable line is coupled to the MTJs for enabling and disabling the differential operation. The MTJ register cell can be connected as a PIPO non-volatile register, a right or left non-volatile shift register, or a multi-bit bi-directional non-volatile shift register.
